The design is inspired by the occupants’ love for the natural scenery of the mountains, through the modern expression technique, combined with the ups and downs of the mezzanine space, it traces the ridges of the mountains and makes the occupants explorers in the mountains and streams. Even in a limited number of acres, people can still feel the fresh and wild nature of reason and gentleness, and retain the heart of loving life and nature. The original layout has a height difference between the living room and the study. In response to the needs of use, the designer sets up a mezzanine above the study, so that the levels of the public and private areas can be distinguished, just like the different stages of the mountain. The rotating TV wall uses dynamic functionality to make the boundary between the study and the living room ambiguous, forming an open and coherent view. Keep a transparent sight in space is the main key in the design. Through the orderly interlacing of iron pieces, the rationality and neatness of modern style are introduced, and the two sides of the mezzanine are separated from the wall surface, creating the image of overhanging mountains and rocks. The bottom step is connected by the gray platform and extends to the study room, becoming a huge rock mass, which can be used as an extended viewing platform and seating area in the living room. It can serve as a desk in the study.
